Yes. Just to kind of not maybe a bit of an overview on inventory. Yes, sorry. A bit of an overview on the inventory in general, as we said, economic inventory, I'd say the cutoff that we have between economic inventory and technical upside is probably, I would say, and you probably imagine this to be true for us. We are maybe a bit on the conservative side. But 1,700 gross locations in economic inventory. What do we mean by economic inventory? We have -- it's got to have a very high confidence in terms of being able to draw a type curve for it. And we have that confidence either from our own experience or offset operators that have good analogs to what we're going to be drilling. The economics include all drilling, completion, equipping and facilities costs, and it's actually burdened with central facilities, which some people don't do, they just stop at ped level facilities, but we include the gathering system, saltwater disposal, we include central tank batteries. And it has to have a 10% rate of return to make it into economic inventory. The technical upside inventory is, as I said in my prepared remarks, it's stuff that it's the next -- it's the next best opportunity for bringing stuff through appraisal and development into the economic inventory bucket. And I don't want people walking away from the call thinking, okay, this is kind of like pie in the sky stuff. Actually, it's not at all. 40% to 50% of our entire technical upside inventory is shallow Delaware Basin. So it's the Avalon and first and second Bone Springs. And in my prepared remarks, I talked about -- there were two wells that we drilled that had pretty promising results. Well, if we drilled those two wells today at our current cost structure for drilling wells, those wells would be breaking even at $41 WTI. And so this is stuff that falls right into the good end of the Skyline plot. That's all -- every bit of that stuff is in technical upside, not in inventory. And so we're going to be drilling a 4-well spacing test later this year in that area. And those are the types of things that we're going to be doing to move technical upside into economic inventory. We actually -- we actually have several appraisal tests or spacing tests going on, both in the Delaware Basin and in the Midland Basin this year for that very purpose, moving quantum of inventory out of technical upside into economic inventory.
